Frederick a. Reutter, Waterbury, Conm, auignor to Scovill Manufacturing compan Waterbury, Conn, a corporation of Connecticut Appucaaonicove ber 11, iesa'sei-m No. 697,605 6 Claims. (c1. era-12's) This invention relates to spools, and more particularly to a sheet metal spool adapted for use in the steamingand soaking of spooled material in the manufacture of textiles such as silk.

One object of this invention is to provide 'a metalspool of the above nature having-a pair ofconcentric tubes supported at their ends in a pair of circular discs, the outer tube being reinforced against crushing stresses. I

A further object is to provide a spool of the above nature which will be simple and strong in construction, have a minimum number. of parts, be inexpensive to manufacture, compact, ornamental in appearance, and very eiiicient and durable in use.

with these and other objects in view, there has been illustrated on the accompanying drawing, one form in which the invention may be conveniently embodied in practice.

In the drawing:

Fig. 1 represents a side elevational view of a winding spool embodying the. invention.

Fig. 2 is an end view of the same.

Fig. 3 is a longitudinal sectional view on a slightly enlarged scale, the view being taken along the broken line 3-3 of Fig; 2, looking in the direction of the arrows.

Fig. 4 is a transverse sectional view taken along the line it of Fig. 3, looking in the direction of the arrows.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numeral it generally indicates'a metal winding spool embo the invention, said spool consisting of an outer cylindrical shell or barrel Ill, a pair of transverse end discs or flanges it and lt,land an inner concentric tubular hub it. The shell it and hub it are preferably each formed of single strips of stainless steel. The inner hub it has its longitudinal side edges abutted and joined by a welded or soldered seam it. The outer shell has a pair of inturned longitudinal abutting parallel flanges t5, the junction seam of which is adapted. to be filled with solder its to provide a smooth joint.

Each of the end discs It and i3 is offset outwardly at its central portion to form an annular boss ill, it. The center of each boss ill, i9 is apertured at Ma, Ma and spun inwardly to form a curved seat for the outwardly spun annular :11 of the hub it (see Fig. 3). For strengthening and stifiening the end discs i2 and i3 and also to eliminate any sharp edges, the peripheral sections thereof are curled over upon themselves to form open beads l9 and 20, said beads lying in substantially the same plane as the bosses l1, l8, so that the spool will have a stable support on a horizontal surface. This construction also permits the spools to be readily stacked.

Shoulders 2| and Ham formed on the discs I! and I3 .at the outer edges of the bosses I1 and I8, to provide suitable seats for the ends of the outer barrel I l, the grooves therebetween being filled up and smoothed by a fillet of solder 23. The bosses 7 l1 and 18 are perforated with aplurality of'circular apertures 24, and the barrel H is provided with a plurality of rows of spaced apertures 25, so that the silk thread or other material wound on the spool will be freely exposed to the action of the steam or other medium to which it is to be subjected.

It has been found in many cases that in drying the spooled thread after it has been steamed,

' the shrinkage of the threadwillexert suflicient compressive force to cause the outer shell or barrel to collapse inwardly unless properly reinforced. For this purpose, each-of the end discs l2 and I3 is provided with a-plurality of integral inwardly extending sheared concave nibs or lugs 26 struck up from the metal at the outer part of the raised bosses W and i8 adjacent the shoulders iii, 22 (see Figs. 2 and 3).

The nibs 26 comprise a plurality of shoulders Eta which are adapted to fit within the' end edge wall of the barrel H at a plurality of spaced points, thus providing a strong reinforcement thereof. If desired, the central portion of the barrel it may also be reinforced. For this purpose, provision may be made of a circular transverse plate t'l, provided with a central aperture with an annular flange 23 for tightly fitting upon the tubular hub it. The plate 21! has a rim slot 28a for accommodating the inturned flanges it of the barrel Ill].

The plate 2'! preferably has a peripheral flange 29 for engaging the interior surface of the outer barrel flIl, said flange serving to hold said plate fromtwisting out of position. The plate 2'! has a plurality of spaced apertures it to allow the circulation of the steam through the interior of the spool. v

Whilethere has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired-to secure Letters Patent is:

1. In a winding spool, a tubular outer barrel, a pair of apertured end plates having axially outwardly offset central bosses surrounding said apertures to form interior shoulders for receiving the opposite ends of said barrel, said plates having a plurality of spaced nibs projecting inwardly from the outer portions of said bosses adjacent said shoulders for reinforcing the edge of the interior wall of said barrel.

2. In a winding spool, a sheet metal shell having its longitudinal edges abutted and welded along a linear seam for forming a tubular spooling barrel, 3, pair of apertured end plates having axially outwardly offset central bosses surrounding said apertures to form interior shoulders for receiving the opposite ends of said barrel, said plates having a plurality of spaced nibs project ing inwardly from the outer portions of said bosses adjacent said shoulders for reinforcing the edge of the interior wall of said barrel.

3. In a winding spool, a tubular barrel, a pair of circular end plates having outwardly formed center bosses to form interior shoulders for receiving the opposite ends of said barrel, said bosses having central co-axial apertures, a tubular hub engaging in said apertures, said end plates having-a plurality of spaced nibs struck inwardly from the body of said bosses adjacent said shoulders for supporting the interior wall of said barrel to prevent collapse thereof under the compressive forces of the thread on said spool while drying.

4. In a winding spool, a tubular barrel a pair of circular end plates having outwardly formed center bosses to form interior shoulders for receiving the opposite ends of. said barrel, said bosses having central co-axial apertures, a tubular hub engaging in said apertures, said end plates having a plurality of spaced nibs struck inwardly from the body of said bosses adjacent said shoulders for supporting the interior wall'of said barrel to prevent collapse thereof under the compressive forces of the thread on" said spool while drying, and a transverse plate on said hub for reinforcing the intermediate section of said barrel.

5. In a winding spool, a tubular barrel, a pair of circular end plates having outwardly formed center bosses to form interior shoulders for receiving the opposite ends of said barrel, said bosses having central alined countersunk openings, a tubular member extending co-axially through said barrel and having its opposite ends spun outwardly upon the edges of said countersunk openings, said plates having a plurality of spaced nibs formed inwardly from the body of said bosses adjacent said shoulders for supporting the end edges of said barrel against collapse, and a transverse reinforcing circular plate within said barrel for reinforcing it against collapse.

6. In a winding spool, a tubular outer barrel, 9. pair of end plates each having an axially outwardly ofl'set central boss, annular shoulders being formed at the outer rims of said bosses to receive the ends of said barrel, said bosses having a plurality of spaced inwardly extending projections at their outer portions for holding the ends of said barrel against said shoulders to reinforce said barrel against inward compressive forces from the material wound on said spool.
